COOLING DEVICE FOR VEHICLE

A cooling device for vehicle includes: an electric motor; an engine cooling pump; a power-control unit cooling pump; and a differential mechanism. The engine cooling pump is configured to allow an engine cooling water to flow by rotary power of the electric motor. The power-control unit cooling pump is configured to allow a cooling liquid for power control unit to flow by the rotary power of the electric motor. The differential mechanism makes a flowrate of the engine cooling pump different from a flowrate of the power-control unit cooling pump by controlling transmission of the rotary power from the electric motor.
